General Information
1.4 Product Description
This device is a single phase grid-tie solar inverter. It converts direct current (DC) electricity from photovoltaic power collected from PV Array into single phase alternating current (AC) to feed the excess capacity back to the local main electrical grid.
This inverter allows wide voltage input range (125~600Vdc for RPI-H3 and 200~1000Vdc
for RPI-H5) and high performance efficiency based on user’s friendly operation design.
In addition, special DSP(Digital Signal Processor)design decreases the circuit complication
and electronic components. Please note that this device does not support off-grid function. The features for RPI-H3/RPI-H5 are shown below.
1.5 How it Works
The operation of solar inverter is shown as the Figure 1-1. In order to save energy and
electricity, solar inverter convert the DC input power supplied from the PV Array into
single-phase AC output power to Grid.
1.6 Additional Information

4.1 Installation Location
Do not install the unit at the location that directly expose to sunlight.
CAUTION Machine and equipment damage may occur
WARNING Death and serious injuries may occur.
● Do not install the unit near/on the flammable objects.
● Please mount the unit tightly on the solid/smooth wall.
● In order to ensure the safety of installers, installer shall be at
least two people to process the installation.
● When moving the Inverter, installer shall not stand under machines.

• Suggested to install the inverter to the location which offers free and safe access. It would streamline the service and maintenance
• Please leave an appropriate gap in between when installing singe/ several solar inverter systems.
• Please install solar inverter at an eye level to allow easy observation for operation and parameter setting.
• Ambient temperature -20°C~60°C.(power derating above 40°C)
CAUTION !
There shall be sufficient space for product operation as shown as the
Figure 4-4. If necessary, installer can increase the gap space for sufficient
operation space.

5.1 Preparation before Wiring
1. Make sure whether the voltage values, polarities are correct.
2. When grounding of the solar array is necessary, an isolation transformer is required due to the RPI-H3/RPI-H5 not having a galvanic isolation between the DC-input and AC-output.
3. The ground fault detection is a fixed internal setting. It always works and can not be modified.
4. The whole system wiring is shown as in Figure 5-1 and Figure 5-2.
5.
Please refer to Figure 5-1 for the connection. Inverter can accept DC inputs in parallel
(1 MPP tracker/2 parallel inputs).

5.2 AC Grid Connection : L + N + PE
WARNING !
Before commencing AC wiring, please ensure AC breaker is switched off.
For RPI-H5, users must aware that AC configuration Setting must be set correctly otherwise this device can not work. There are two types of AC configurations (shown in figure 5-3) that are used in electricity systems. For “AC Configurat.” setting please see chapter 7.2.2
Star configuration (3 phases + Neutral): L–N (default), The voltage between each phase and the neutral is 230/220 V. The voltage between two phases is 400/380V.
Delta configuration (3 phased wires only) : L–L, The voltage between two phases are 230/220V. As there is no neutral, there is no phase-neutral voltage.

Active/Reactive Power Control and LVRT (Optional)
6.1 Active Power Control
6.1.1 Power Limit
Users can reduce inverter output power by set percentage of actual or rated power.
There are 2 settings for active power and 4 settings for reactive power control based on the requirement from network operator.
6.1.2 Power vs. Frequency
According to VDE-AR-N 4105 (5.7.3.3)
At frequencies between 50.2Hz and 51.5Hz, all adjustable power generation systems shall reduce (for frequency increase) or increase (for frequency decrease) the active power Pm generated instantaneously (at the time of exceeding the mains frequency
50.2Hz; freezing the value on the current level) with a gradient of 40% of Pm per Hertz).
According to CEI 0-21 (8.5.3.2)
Within a frequency range from 50.3Hz to 51.5Hz, all adjustable production plants equipped with static converters have to be able to reduce the currently generated active power in case of an increase of the frequency with a variable droop of 2% to 5% with a default value of 2.4% (with corresponds to a power gradient of 83.3%/Hz).
User can set all necessary settings to meet the requirements from network operator. Please refer to actual Power vs. Frequency for the settings procedure.

6.2 Reactive Power Control
With active power output, it must be possible to operate the generating plant in any operating point with at least a reactive power output corresponding to a active factor at the network connection point of
cos ϕ = 0.8 underexcited to 0.8 overexcited
(VDE-AR-N 4105,CEI 0-21 cos ϕ = 0.9 underexcited to 0.9 overexcited)
Values deviating from the above must be agreed upon by contract. With active power output, either a fixed target value for reactive power provision or a target value variably adjustable by remote control (or other control technologies) will be specified by the network operator in the transfer station. The setting value is either
1. fixed power factor cosφ (VDE-AR-N 4105 ,CEI 0-21)
2. displacement factor/active power characteristic curve cosφ(p)
(VDE-AR-N 4105 ,CEI 0-21)
3. fixed reactive power in Var.(CEI 0-21)
4. reactive power/voltage characteristic Q(U). (CEI 0-21)
30
Active/Reactive Power Control and LVRT (Optional)
6.2.1
Fixed Power Factor cosφ (VDE-AR-N 4105,CEI 0-21)
Users can set power factor from Cap 0.8 to Ind 0.8 (inverter would stop reactive power control if output power is below 20% rated power).
6.2.2 cosφ(P) (VDE-AR-N 4105,CEI 0-21)
Once user enables this method, inverter will deliver reactive power according to output active power at that moment. Figure 6-2 is an example.
6.2.3 Fixed Reactive Power In Var.(CEI 0-21)
Once user enables this method, inverter will deliver reactive power (ie. Q) according to the fixed reactive power setting. The setting range is from Cap 48.4% to Ind 48.4%.

7.1 Start-up Procedures
WARNINGBURN HAZARD!
The enclosure temperature may exceed over 70°C while operating. Danger may occur owing to hot surface. Please do not touch! After installation, please confirm the AC, DC, and Communication connection are correct. When solar irradiation is sufficient, the device will operate automatically after no mistakes on self-auto test (about 2 minutes at 1st startup of a day). The display includes 16×2 LCD display and LED indicator for inverter status. There are green and red colors for LED indicator to represent different inverter working status.
7.1.1 PV Array DC Voltage Checking
1.
Uncover the PV arrays and expose them to full sunlight. The sunlight must be intense
enough to produce the required output voltage.
2. Measure the PV array open circuit DC voltage across the DC positive (+) and negative (-) terminals.
7.1.2 AC Utility Voltage Checking
Using an AC voltmeter measures the AC open circuit utility voltage between L1 (L) and L2 (N). Ensure the voltage is at approximately the nominal value. The inverter operates with a line-to-line voltage range around the nominal value.
See “11. Technical data”, output section for the utility voltage operating range for your inverter model.
7.1.3 Starting up the Inverter
1.Switch the DC and AC disconnection switches (breakers) to “ON”.
2.Check the inverter LCD. The startup screen should appear in several seconds, (for the first time start up, select proper country and language. See “7.3.2 Country Selection & 7.3.3 Language Selection”).

8 Maintenance
In order to ensure the normal operation of PV Inverter, please check up regularly at least once each year or each half year. Check all the terminals, screws, cables are connected well. If there are any impaired parts, please contact with the qualified technician to repair or replace to the new spare part. To ensure that no foreign body stocks at the heat outlet, please clean up once a half year by qualified technicians.
WARNING Death and serious injuries may occur.
Before maintenance, please must disconnect AC and DC to avoid risk of electronic shock.
